matconvnet-oneclick's Introduction

MatConvNet训练自己的数据

当前几乎所有主流的开源深度学习工具都做了一个非常强的假设:用户会自己去看源代码,也就是所谓的代码是自解释的。

其实真的也没什么难的,就是按照基本流程来就好了:

无外乎准备数据,设计网络结构,开始训练,最后是验证训练的结果。

MatConvNet示例数据都是很常用的,mnist、cifar等有自己的存储格式,按照它给的定义解析出来就好了。ImageNet太大,100多G,小课题组没有强大的装备不可能去实现,也没那个必要。

这里给出的示例相对而言还是比较科学的,把每个类别的数据放在同一个文件夹下,然后依次读取,并划分训练集和验证集,只不过还缺少一个随机打乱数据顺序的过程。

网络结构可以参考已有的结构,稍加改动,训练就一句代码搞定。

验证训练效果的话也可以参考已有的例子实现。
